According to the National Weather Service, a watch means that a tornado “is possible,” so be prepared.

"This is issued by the National Weather Service when conditions are favorable for the development of tornadoes in and close to the watch area. Their size can vary depending on the weather situation. They are usually issued for a duration of 4 to 8 hours. They normally are issued well in advance of the actual occurrence of severe weather. During the watch, people should review tornado safety rules and be prepared to move to a place of safety if threatening weather approaches." — National Weather Service

Last Tuesday, tornadoes hit Nashville overnight. At least 24 people were killed and more than 140 buildings were destroyed, authorities reported.

According to weather data, the spring is the most common time for tornadoes to hit the South. March begins a stretch of stormy weather that lasts until July.

"While the typical tornado season is often thought of as the peak months of April through June, most months have featured significant tornado events at one time or another." — U.S. Tornadoes website

Forty-three percent of all tornadoes from 1991 to 2015 happened in the spring, and an average of 75 twisters touch down in March alone.
